Specification of Letters Patent.

Patented Oct. 11, 1910.

Application filed December 6, 1909. Serial No. 531,620.

To all whom it may concern:

Be it known that I, ANTHONY I-IAAG, a citizen of the United States,residing at Bronx, in the county of New York and State of New York, haveinvented certain new and useful Improvements in Plumbing Apparatus forConcrete-Wall Molds; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in plumbing and adjustingapparatus for concrete wall molds.

The object of the invention is to provide an apparatus by means of whichthe molds or forms for concrete walls are adjusted and firmly held inposition while being filled with concrete and which may be employed inthe construction of either hollow or solid walls.

lVith the foregoing and other objects in View, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claims.

In the accompanying drawings: Figure 1 is a vertical sectional view ofthe lower tier of forms showing the arrangement of my adjustingapparatus before the concrete is applied to the forms. Fig. 2, is asimilar view after the concrete has been applied to the lower tier offorms and the upper tier of forms arranged thereon to receive the secondcourse of concrete. Fig. 3, is a detail perspective view of one of theplumbing standards. Fig. 4 is a similar view of one of the form holdingand separating bars for maintaining the forms in place while beingfilled. Fig. 5 is a similar View of the plumbing and separating bar forthe tiers of forms above the first tier. Fig. 6 is a similar view of oneof the metal ties for holding the sections of the wall together afterbeing formed and which also serve to hold the lower end of the plumbingstandard and to separate the same while in use. Fig. 7 is a plan View ofone of the washers used in connection with the tie. Fig. 8 is a detailperspective view of one of the plates for holding the ends of the formstogether.

In the embodiment of the invention, I provide a suitable number of formswhich are preferably in the form of steel plates 1, of suitable size andthickness, which are arranged at suitable distances apart to form a wallof the desired thickness. WVhen a solid wall is to be formed, I employsimply an inner and outer series of plates 1 and when a hollow wall isto be formed, additional plates are used and are arranged a suitabledistance apart between the outer plates to form a space of the desiredwidth between the two sections of the wall.

In forming the wall, strips 2, of wood, of suitable size are laid alongon top of the concrete footing or base 3, of the wall at the properdistance apart after which tie bars 4, hereinafter more particularlydescribed, are laid upon the footing between the strips 2. The outerforms or plates of the lower tier are then set up on the concretefooting and tie bars and against the inner edges of the strips 2, asshown. When a hollow wall is to be formed, inner plates or forms 1 areset up on the footing and tie bars at suitable distances apart andspaced from the outer plates the required distances for forming theinner and outer sections of the wall.

The tie bars 4, are in the form of strips of metal of suitable width andthickness and of sul'licient length to reach across the width of thewall to project beyond the outer sides of the same. in the projectingends of the bars a, are formed square holes 5, in the outer edges ofwhich are formed notches 5, the purpose of which will be hereinafterdescribed. ln the bars, at a suitable distance from each side of thecenter thereof, are outwardly projecting pairs of parallel ears or lugs5 which are preferably formed by cutting semi circular slits in the barsand bending the cut metal upwardly, as clearly shown in Fig. 6, of thedrawing. When the forms 1, are set up for use, the lower edges of theinner forms are engaged with and held in position by the parallel ears5, of the tie bars.

The outer plates or forms of one side of the mold are held or supportedin an upright position by means of plumbing standards 6, the lower endsof which are reduced and are engaged with the notches 5 in one end ofthe tie bars at. The upper portions of the plate or form on the oppositeside of the mold and the intermediate plates or forms are supported andheld in spaced relation with each other by means of spacing bars 7. Thebars 7, are preferably T- shaped in cross section-and in the lowerportion of the same are formed a series of notches 8, which are engagedwith the upper edges of the plates or forms 1, and thereby holding thesame in adjusted positions. In 1 the opposite sides of one end of thebar 7,

is formed a series of notches 9, which are adapted to be engaged wlththe plumbing standards 6, adjacent to the upper edges of the plates,thereby holding the plumbing standards in close engagement with the ad-3 In addition to the separating bars arranged opposite each of 5 theplumbing standards, I may also employ any suitable number ofintermediate spacing bars arranged in between the bars which engage thestandards. The plates or forms are preferably secured together by smallmetal plates 1 having punched from and formed thereon hooks 1 which areengaged with suitable holes formed along the adjoining edges of theplates. The lower ends 1 of the standards 6, when forming the firstcourse of concrete, are preferably secured to the wooden strips 2, bystaples or other suitable fastening devices.

After the concrete has been applied to the lower forms of the molds andhas sufficiently set or hardened, the inner forms or plates and thespacing bars 7, between the standards 6, are removed. After these partshave been removed, the spacing bars, opposite each of the plumbingstandards, are retie bars a, constructed as hereinbefore described. Inapplying the tie bars, one of the apertured ends thereof is slipped overthe upper end of the plumbing standard and said bar is then brought downonto the upper edges of the outer plates or forms and onto the firstcourse of concrete. After the bars have thus been brought down, thenotch 5 of the hole 5, which is applied with 1 the standard, is engagedwith a notch 11, formed in the outer edge of the standard, adjacent tothe upper edge of the side plate or form, thus providing an interlockingconnection between this end of the tie bar and the plumbing standard.After the tie bar has thus been engaged with the standard, a flat washer12, which is preferably of rectangular form, is slipped to the oppositeend of the bar and is forced up into engage ment with the outer side ofthe adjacent outer form or plate 1, of the mold by a linch pin 13, saidpin having a reduced lower end which is inserted in the notch 5 of thehole 5, at this end of the bar. When the tie bars have thus beenarranged, the plates or forms 1, for the second course of concrete, areset up on the tie bars. The outer plates or forms are in line with theouter plates of the lower course of concrete, while the inner plates orforms set into or between the ears 5 of the tie bars and the lowerportions of the same are thereby held in proper position to form a spaceimmediately above the space of the lower course. The outer side platesof the side of the mold, adjacent to the plumbing standards are held attheir lower edges by the upper end of the vertical portion of saidstandards while the lower edges of the outer plates or forms of the opposite side of the mold are held in position by the washers 12, on the tiebars lVhen the plates or forms of the second tier have been thusarranged, the upper portions thereof are adjusted and spaced the properdistance apart and plumbed perpendicular or held at any suitable angleby plumbing and spacing or separating bars 1 1, which consist of flatstrips in one edge of which are formed a series of notches 15, whichcorrespond with the notches formed in the spacing bars '7. One end ofthe plumbing and spacing bars 1 1, is extended and projects a suitabledistance beyond the side plate or form adjacent to the plumbingstandards and in said extended end is formed a slot 16, with which isengaged a clamping bolt 17, inserted through a bolt hole 18, in the endof an angular or inclined extension 19, formed on the upper end of thevertical portion of the plumbing standards 6, as shown. On the end ofthe bolt 17, is screwed a thumb nut 20, which is adapted to be screwedup into tight engagement with the extended end of the spacing moved and1n place thereof, are arranged l and plumbing bar 14, after the latterhas been adjusted to bring the plates or forms of the mold in properposition. In addition to the spacing or plumbing bars let, I may also,if necessary, employ any number of the spacing bars 7, in between thebars 1 1, to hold the upper edges of the second tier of forms inposition and prevent the bulging of the same while being filled withconcrete. After the second course of concrete has thus been laid, theinner forms and the spacing bars are removed, as hereinbefore described,and the plumbing standards are also disengaged from the lower tie barsand are moved upwardly and have their reduced lower ends engaged withthe notches and apertures in the projecting end of the next row of tiebars, whereby said plumbing standards are supported and held in positionin the same manner as described in connection with the forming of thefirst two courses of concrete. After the plumbing standards have thusbeen moved upwardly, the outer forms or plates of the finished lowercourses of the wall are removed and the projecting ends of the tie barsare cut cit. By successively repeating the operation hereinbeforedescribed, walls of any desired height may be quickly and easilyconstructed.

It will be noted by reference to Fig. 1 of the drawings that when thefirst course of the wall is constructed, the plates or forms 1 arebraced and held in position by plumbing and separating bars 14, saidbars being swung downwardly on the bolt 17 until their opposite ends arein engagement with the spacing bars 7 to the ends of which theseparating bars 14 are secured by wiring as shown or by any othersuitable connection. This arrangement of the plumbing and separatingbars 1 1 applies only to the first round or course of forms, saidplumbing or separating bars being engaged with the upper edges of theforms or plates above the first round or course, as shown in Fig. 2 ofthe drawings.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended claims.

Having thus described my invention, what I claim is 1. In an apparatusof the character described, a plurality of mold plates or forms, aspacing bar, said bar having formed therein a series of vertical andhorizontal disposed notches, said vertical notches being adapted to beengaged with the upper edges of the plates or forms, a plumbing standardadapted to be engaged with the horizontal notches in said bar, andhaving a diagonal offset end, a notched spacing and plumbing bar adaptedto be engaged with the upper edges of the upper tiers of plates orforms, and means whereby one end of said bar is adjustably secured tothe offset end of said plumbing standard, whereby the upper tiers ofplates are held in perpendicular position or at any desired angle.

2. In an apparatus of the character described, a plurality of moldplates or forms,

footing strips adapted to be engaged by the lower edges of said plates,spacing bars adapted to hold said plates in proper position, a series oftie bars having apertured outer ends and adapted to be engaged with theupper edges of one tier of mold plates, means on said bars to hold thelower edges of the next adjacent tier of mold plates, a series ofplumbing standards having vertical lower portions and obliquely disposedupper portions, said vertical portions being engaged and held inposition by the apertured portions of one end of said tie bars, spacingand plumbing bars having formed therein a series of notches to engageand hold the upper edges of the upper series of mold plates in position,a slotted extension formed on one end of said spacing and plumbing bar,a clamping nut arranged in the obliquely disposed upper end of saidplumbing standard and engaged with the notch in the extension of saidplumbing bar, and a thumb screw on said bolt to hold said plumbing barin its adjusted position to support the upper series of mold plates in aperpendicular position or at any desired angle.

3. In an apparatus of the character de scribed, a plurality of moldplates or forms, a series of spacing bars, said bars being T- shaped incross-section and having formed in their side edges a series ofhorizontal notches, a cross bar or head arranged on one end of saidspacing bars, whereby when the vertical notched portion of the bars isengaged with the upper edges in said mold plates, said cross-head willengage the upper edge of the outer plates of one side of the mold, andthereby hold said plates against bulging While the forms are beingfilled with concrete, plumbing standards each having a diagonal offsetend and adapted to be engaged with the horizontally notched portions ofthe opposite ends of said bars, and a series of notched plumbing andspacing bars adapted to coact with the offset end of said plumbingstandards to hold the upper edges of the upper series of plates or formsin perpendicular position or at any desired. angle.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
